Application June 5, 1945, Serial No. 597,666

This invention relates generally to envelopes, and specifically to dualpurpose envelopes for mailing to an addressee, and remailing to theaddressor. s

It is customary for many business houses in mailing out merchandise,statements, premium notices, installment payment or loan notices, etc.,to enclose return envelopes to be used by the receiver to'forward neworders or checks to cover statements or notices. There are manydifficulties which accompany this procedure. Care must be taken toinclude a return envelope with the matter inserted in each forwardingenvelope. Bills, statements, premium notices, etc., must be separatelypurchased, stock maintained, plus the additional labor of folding beforeinsertion. The receiver often fails'to place his address upon the returnenvelope, and thisycoupled with the fact that he frequently neglects toenclose the identifying portion of the notice or statement as requested,makes identification of the, sender diflicult. Neglect on the part ofthe customer to notify the business house of changes of address leads toincorrect records and misdirected and, therefore, delayed mail.

The object of this invention is to provide a dual purpose envelope whichmay have inscribed thereon, before mailing, the name and address of boththe addressee and the addressor, with that of the addressor beingcovered while the envelope is being forwarded to the addressee anduncovered by the act of rescaling for return to the addressor.

Another object of the invention is to provide such an envelope whereinthe rescaling of the envelope for return to the original sender willuncover the address of the original sender and cover the address of theoriginal addressee, including any corrected or changed addresswhich thepost office may have noted thereon.

A further object of the invention is to provide an envelopeincorporating these features which also provides means wherebyconfidentialrinformation forming a, document of original entryfacilitating the identification of the remittors account and properaccounting credit thereto may be placed upon the envelope andcoveredduring transit to the addressee; the act of opening the envelopedisclosing the information to the recipient and the act of rescaling theenvelope for return again hiding the information from view.

A still further object of the invention is to providesuch an envelopehaving as an integral part thereof -a.plurality of sheets for receivingdupli- 12 Claims. (01. 229-73) cate impressions of the information andaddress placed upon the envelope, the sheets being superimposed forcarbon impressions. or adjacently arranged for successive impressions incertain types of addressing and billing machines.

An object of the invention is to provide such an envelope wherein theopening of the envelope is facilitated to insure its proper opening andpreclude the possibility of accidental destruction of the return portionor mutilation of the information carried by the envelope.

In general, the object of this invention is, the provision of anenvelope which may be usedas a forwarding vehicle and as a returnenvelope, and which may contain certain information valuable to originaladdressee andaddressor alike, which information cannotbecome separatedfrom the envelope and is hiddenfrom public view during transit andserves as an important basis of accounting credit. 5

The. window is not covered and: the f surface-'--of the"clo'sure' fiap 1' is visiblei'therethrough. K I V"Before'proceedin'g with a-descriptionioi the use of the envelope, itshould be stated that prior tofiadheri'ng the cover sheet "to the*envelope and before the closure flap is folded'h'ack on tlie line HLthe name and address of the business -house purchasing the envelopes isprinted on the front panel of the basic envelope in the manner nowpracticed with return envelopes. This address is indicated at I! inFigure 6 of the drawings. After this is done, the flap 1 is folded downinto position and the cover sheet secured in place before shipment tothe purchaser.

In use, the envelope may be inserted into a typewriter or addressingmachine and the name of the addressee marked upon it in the spacedefined by the window [6. As this window is not covered, the addresswill be placed upon the flap 1 which shows through the window. A notice,bill, or other material is then inserted into the pocket portion of thebasic envelope found between the front and back panels 4 and 3, and theprimary closure flap I4 is folded over the back of the basic envelopeand sealed, as is shown in Figures 2 and 3. Upon receipt by theaddressee, a letter opener or the finger is inserted at the notch l5 andthe envelope slit across the top along the fold line between the coversheet and the closure flap in the usual manner. The notch 15 forms aguide to aid in starting the slit properly and thus prevent damage tothe remaining portion of the envelope. As soon as the envelope is slit,the front face, or cover sheet, is peeled off, as shown in Figure 4.This reveals the return envelope. Slitting the cover gives access to thepocket portion of the envelope, and the bill or notice contained thereinmay be removed.

The stub of the bill or notice may then be reinserted in the pocketportion of the envelope along with a check or money order and the flap 1turned over the top of the envelope and sealed against the back panelready to be mailed back to the original addressor. Although the primaryclosure flap [4 remains attached to the back panel of the envelope, thelarger flap 1 will cover the flap [4, and its gummed area will beattached to the back panel of the envelope.

It will be noted that the forwarding address which was typed through thewindow in the cover sheet onto the flap 1 is on the underside of theflap when the flap is in sealing position for return to the addressor.It will also be noted that the address of the original addressor whichis printed upon the front panel of the basic envelope is revealed byfolding the flap into sealing position.

Upon return of the envelope to the original addressor, the envelope isopened in the usual manner by slitting across the top. The V-notchesprovide a guide for beginning the slit, and the weakened line 8 betweenthe cover sheet and the closure flap ensures the slit occurring at theproper place and also prevents a ragged tear. The closure flap 1 isprovided with a second perforated, or weakened line [8, extendingtransversely across the flap just above the gummed portion of the flapand below the position occupied by the address of the originaladdressee. After slitting the envelope along the line 8, the flap may betorn off along the line [8, thus furnishing a neat slip to accompany thecheck for purposes of identification. This slip will contain the nameand address of the customer as Well as any change of address which thepostal authorities may have marked upon it. This will serve to identifythe account as well as furnish the necessary information to keep themailing lists up to date.

Now referring to that form of the invention shown in Figures 9 to 14inclusive, a basicenvelope l'9 of any standard design is employed. Thisenvelope ingeneral consists of front and back panels 20 and 2|, and aclosure flap 22. A cover sheet is used with this form also, but itdiffers somewhat from that in the form just described. The cover sheetis designated 23 and comprises three sections: a relatively thin section24 which is attached with adhesive to the front panel 20 of the envelopeabout midway between the top and bottom edges of the envelope andextends thefull Width of the envelope; 2. main section 25 projects fromthe section 24, which is coextensive with the envelope in Width andextends downward to a point near the lower edge of the envelope; and, asecondary closure flap 26 folded under the main section 25 to liebetween the mainsection and the front panel of the basic envelope. Theflap 26 is reduced in width, as was the flap M of the first form. Theunderside of the main panel 25, at the side edges in the margin notcovered by the narrowed closure flap, is provided with adhesive spots21, which attach the main section of the cover sheet to the front panelof the basic envelope. Thus the secondary closure flap 26 is securelyheld in place under the main section of the cover sheet.

This envelope may be placed in a typewriter in the usual manner and theforwarding address typed upon the face of the main section25 of thecover sheet, in the position shown in Figure 9. When delivered, therecipient will open the envelope in the usual manner by slitting acrossthe top. To convert the envelope to a return envelope, the cover sheetis grasped at the lower edge and lifted, breaking loose the adhesivespots 21. The fact that the cover sheet terminates slightly above thebottom edge of the envelope provides a selective grip, making it veryeasy to do this. The main section of the cover sheet is then folded upalong the fold line 21 and the closure flap 2% is folded over the top ofthe envelope. This is clearly illustrated in Figure 12. After thedesired insertions have been made in the pocket portion, the closureflap is sealed. As in theform previously described, the secondaryclosure flap is larger than the primary closure flap so that the gummedarea of the secondary flap will not adhere to the primary flap. When thecover sheet is lifted and the envelope resealed, the address of theoriginal addressor is revealed and the address of the originaladdressee, original postage, return address, etc, concealed on theunderside of the cover sheet.

That form of the invention shown in Figures 15 to 18 inclusive is quitesimilar to that shown in Figures 1 to 8, and the same referencecharacters are applied to similar parts. The basic envelope is identicalto that of the first form and the cover sheet is the same in outline andmethod of attachment to the basic envelope. However, in this form of theinvention, the vertical side cuts made in forming the window I6 arecontinued above the window as at 28 and, with a line of fold 29, definea tab 30 which may be lifted to expose additional surface of theunderlying closure flap 1. The underside of the tab 30 is provided witha blockout area 3| which may be solid black or any heavily printedmarking which will make it impossible for confidential information to belegible through this area. The lower edge of the tab 30 is gummed sothat it may be adhered to the face of closure flap 1 when the tabisfiowered. A perioratedtear i-ine 3-2 separates 'the-giiimhed andblocltpiit areas,

' rivelope is inserted in a typewriter with tab 30 folded back-in-the-positionshownin" Figures and -16, and the forwarding --addr'essis typed'in the lower-"part oi' the window opening. On themart'ot theclosure'fia p l which-is e);- posed' in theupper part ofth'e window andwhich will be hovered by the tab when -folded down, confidential'iniornation,such as the-' amount of {a bi ll or premiumfrnay be "typed.After-the fenvelepe has been re'r'noved fromthe typewriten the tab"is-f0l ded downand the s mmed portion adhered to the'closure flap '1.This effectually conceals the confidential information durin 5 transitto the addressee.

v Upon receipt, the envelope is-slit and" the cover sheet peeled off,thetab 30 beingworn along the --perforated line 32' inthe sameoperation. This will reveal allot-the informationto the'recipient.

After-the proper check has been inserted 'in the pocket portion, theclosure fiap iis foldedover and s'ealed ashas been described.

This form of the invention has a number of advantages. Not only does iteliminate-the use'of 1 two envelopes, but it also makes the use ofseparate bills, "etc. unnecessary. It has 1 thefurther advantage ofhaving the amount of the bill and any other desired information inaconcealed portion-on the secondary flap ofthe envelope, which "ensuresthis information being returned withthe =payment to serve inidentifying-and properly crediting the-remittance. This is accomplishedwithout" the use of carbon paper, etc.

) Figures 19 to 22 inclusive showanother for-moi the invention. Her-ethe pocket portion of the invention is the same as in the firstform,-having front and backpanels 33 and 34, and a secondaryclosure'flap35 extends from the front panel'as before. The cover sheetin this form is a continuation of the back panel 34 and forms a pri-"mary closure fiaptfi. The backof the cover sheet 'isfprovided with arectangular carbon spot -37 centrally locatedi and or sufficient area tocover the space which is to beutilized for the address "andconfidentialinformation which is to be placed "on the envelope.The-cover sheet-is gummed on its lower arid side-edges asat'BB, for ad-"her'en'ce to the front-panel of 'thebasicenvelope when-the envelope isto be sealed. The cover sheet m aybe cut out to embrace the space to besea for confidential-data to let the black sur- "faceof the-carbon sheetshow'through as a conbealingblock out," or this space may-be blockedout, as at 39, by heavy printing. It is necessary "that some ineans beprovided to'hide the" typing whichisfto beplaced in this area, andeither of the foregoing methods will suflice.

In use, this envelope is placed in the typewriter and the address placedjustiaelow the blo'cked out'space 39. Theamountof the'billor payment istyped in--the blocked out space 'or "black carbon surface'wherethe'he'avy printing will effectually hide it. All of the typing will bereproduced on the secondary closure flap bythe "carbon s'pot3l. Thus theforwarding address appears on both the cover sheet'and the secondaryclosure flap and" the confidential 'materiaris legible only on thesecondary closure flap. The "enve'lope'is' then sealed by moistening theadhe- "sive 38 and securing the cover sheet in place.

Upon recepit, theenvelope is slit and the'cover feet isfpeeled ofirevealing the'inforrnation car- -hledbn the" closure flap. The secondaryclosure folded against the underside ofthe facing sheet so as tolee-obscured from view-'when the cover sheet is -afli'x'ed 'to "thebasic envelope. The 'addressis' typed upon the f ront ot'the covei-sheet and the envelope sealedby means of the-closure fiapdii. The.envelope is slit upon receiptand the cover sheet peeled 0 1i. ZI-n thisformfithe cover sheet is not discarded; for when the 'e-Site'nsionisfolded cow-11. 1am: rear side or "the cover sheet forms an orderblankwl-iich may be convenientlyused when anew supplyof-goods -isneeded. After the order blank is filled out, it

is inserted in the pocket portion ofthe: basic return envelope andtheenvelope sealed-'by means 'of'the secondaryclosure flap. Thisformoforder blank identifies th purchaser whose 1 signature may beillegible by-ineans'of the original address appearing on the back,togetherwith any forwarding address entered on it by the postalauthorities in itsoriginal delivery. Thu custerrier mailing addressesmaybe brought up-todate.

Figures 27 to'3l show aiormof; envelopeby means of which an officerecord is provided simultaneously with the addressing of the envelope.This form also shows means whereby a single'impres'sion will reproducenecessary data on certain parts of the envelope and omit it from otherparts where it is not desired.

The'constructio'n of the envelope is similar to the first formdescribed,'the only=e iceptionbeing an additional sheet 45 attached tothe'lower edge of thecover sheet-and separable therefrom-along aperforated'line-dt. The "sheet 45" is'an 'oiiice record and is attachedto the envelope ior'cone i nc n h se v sheath-rmvidedwith a relativelylarge carbon-spot'AT on it underside which will serve to reproducedataonto the closure flap of'the basicenvelope. The ofiice record sheet isalso provided with a-carb'on spa is smaller in area than the' spot 41."The carbon spot 48 is placed-on that'side of the off ce record sheetwhich will contact the cover sheet when the record sheet'is folded upalon theline Atyas is shown'in'Fig'ures 2'7. and 28. It will be notedfrom the dotted'line showing in Figure 27 that the outlines andpositions of the carbon spots 41 and Marc such that they overliea'comjmon area; Within the outline of spot .48, but that thespot 47,being larger, covers an additional fi linginala'r'ea at the sides andtop of; the $1 01 48.

This envelope'isplaced in a" typewriter with the ofifice record-sheetfolded up againstithe' cov- "er' sheet. The required information andaddress are typed. Figure 27 shows the positionof the data: upon therecord-sheet. It can be seen that the address is placed in that areawhich is framed by both carbon spots so that duplicate impressions willbe made on both the cover sheet and the secondary closure flap carriedby the basic envelope. The confidential information is typed outside thearea occupied by the carbon spot 48 but within the outlines of thecarbon spot 41. This information, therefore, will not appear on thecover sheet but only on the secondary closure fiap. After the typing iscompleted, the envelope is withdrawn from the typewriter and the officerecord-sheet detached for filing. The envelope is then handled in themanner of those previously described.

Addressing machines are designed to make duplicate impressions upon aplurality of joined :sheets. Some feed from the side and operate upon aseries of laterally extending sheets.

Others feed from the front, and the sheets are arranged one above theother. Either of these arrangements may be used with the envelope of thepresent invention. The sheets would be attached either to the bottom ofthe cover sheet or at the side edge. For purposes of disclosure. onlythe side-extending sheet is shown. However, a description of one formshould serve for both.

Figures 32 to 37 show this form. The cover sheet 49 is one of a seriesof connected sheets, the sheets being separable along a perforated line50 for detachment from the cover sheet. The blank 5| may be an oflicerecord. As indicated in Figure 32, this form of the invention is readilyadaptable to use in mailing out premium notices or the like.

Contrary to the practice described hereinbefore, the address andconfidential information are to be placed upon the back panel of thebasic envelope. This panel is, therefore, printed in any desired mannerto correspond to the ofiice record-sheets which are attached to thecover sheet and are to receive duplicate impressions of the materialplaced upon the back panel of the envelope. After the envelope andattached sheets are run through the addressing machine, the officerecord is torn off.

As the back panel of the envelope contains confidential information aswell as the address, means must be provided to obscure the confiden-'tial information while leaving the address visible. To accomplish thisthe primary closure flap 52 attached to the cover sheet is of slightlydifferent design. The closure flap must be of suiiicient length to coverthe confidential information. It must also have a gummed area 53 which 1must not encroach upon the areas occupied by this information nor by theaddress. The gummed area, therefore, extends transversely across thelower portion of the closure fiap with the upper edge of the gummed areacontacting the back panel of the envelope just below the positionoccupied by the confidential information. As most addressing, orbilling, machines place the address rather closely below the billing orpremium amount, the lower edge of t e closure flap must be cut away toform an arch 54 to frame the upper portion of the address. This leaves arelatively thin section of gummed surface 55 bridging the space betweenthe wider areas 55. The gummed area is separable from the remainder ofthe'fia along the perforated line 51. A block-out spot 58 is provided onthe flap to overlie the confidential information to make it impossibleto read this information through the closure flap.

' It will be noted in Fi ures 34, 35 and 36. w ich shows the cover s eetside of the en elope, t at the cover sheet 49 is provided ith a line oferforations 59 running horiwontallv across the sheet and spaced from theupper edge of the envelope a distance slightly greater than the lengthof the secondary closure flap 60 attached to the basic envelope. Whenthe envelope is received by the original addressee, he will insert hisfinger or-a letter opener into the space provided by notch 6| and tearthe flap along line 51. This releases the flap from the adhered gummedportion so that it may be raised to reveal the hiddeninformation. Theflap and the upper portion of the cover sheet may then be removed alongthe line 59 and discarded. This uncovers the secondary flap 60 andfreesit for use in resealing theenvelope. 1

The secondary closure flap 60 is similar in shape to the primary closureflap 52, so that when the envelope is resealed, the confidentialinformation on the back panel of the basic en velope will be covered asbefore. the secondary closure fiap into'sealing position uncovers thereturn address which is on the'front panel of the basic envelope. Inthat form of. the invention shown in Figures 38 to 43, the envelope isquite similar to that of the form just described. The primary purpose ofthis form is for use where a plurality of record sheets are to be markedby a single impres-- sion. A number of sheets 62 are provided in bookform; each of the sheets having a stub 63, the main portion of thesheetsand the stubs being separable along a perforated line 64. All ofthe stubs are adhesively fastened together, the main portion of thesheets being free from one an; other. The back sheet of the groupispasted; or otherwise secured, to the back panel of'the basic envelope insuch a position that the perforated line 64 is in alignment with oneedge of the envelope. The envelope may be placed in a type writer andany desired information placed there on, including the address. Whenthis is completed the 'operator will grasp the envelope in one hand andthe'stubs 63 in the other and by a quick pull separate the lower sheetfrom the balance of the book. The primaryclosurefiap of the envelope maythen be folded over and the envelope sealed as usual. The remainingsheets of the group may be used at various times to form address. sheetsto be pastedon the front'of additional unmarked envelopes, which mayserve as follow-ups in case a remittance is not received in response tothe original bill, without the ne-' cessity of retyping' the laternotices, bills, etc. and insuring their return with any remittance for?its identification and credit.

While in the above several modifications of the invention have beenshown and described,'it' is to be understoodthat various changes maybemade from the precise structure disclosed with-- out departing from thespirit of the appended claims. What I claim is: v 1.
